Noilly Prat is my preference. It is more or less the same price as Rossi. I like to keep it in the fridge. I feel it keeps it fresher. Fortunately orange bitters are easily available at any better liquor store. I remember having to search like crazy for them 10 years ago.

As for the 2/3 to 1/3 gin to vermouth ratio, feel free to play with it. I like vermouth, but that is a LOT. Personally, I like 3oz gin to 1/2 oz vermouth.

Here is another recipe I just discovered last night, but haven't tried it yet.

Re: How do you like your martinis?

Yes, those are blue tipped olive picks (showing a little wear in the picture, although not so evident to the naked eye) with a blue based glass and bleu cheese stuffed olives for my Bombay Sapphire dirty martini (Dolin vermouth). I know, looks more like an hors d'oeuvre than a drink. So be it. It's tasty. Even got a couple of ice shards to form in the shaker.
